'To all lwhom it may concern:

11 Be it known that l, FRIEDRTCH JOHANN DITRICH HLLINGHoRsT, a subjectof the Emperor of Germany, of 190B1ythe road, West Kensington Park,London, in the county of Middlesex, England, have invented anewanduseful Improvement in Radiators or Coolers yfor Motor Road-Vehicles,of' whichfthe following is a specification.

This invention relates to radiators or coolers for motor road vehicleswhereby the temperature of the Water which is circulated about theengine cylinders and other parts of such vehicles to be cooled isconsiderably reduced and overheating prevented,

The resent mvention has reference more especia l-y toradiators orcoolersof this class such as are described in thespecificationaccompanyinginy application for LettersrPatent dated March13th, 1907, Serial Number Radiators or coolers of the kindabove re-`ferred'to have-comprised an air-.propelling fanin combination with anannular chamber or chambers and supplemental cooling-.spaces arranged atthe front and `back of the ,radiator; said chambers and sup spaceslbeingfurnished wit i inter-communic'atingrpipes or;connections,.and .thespace; at the back: of `the .radiator being perforated,somewhatvhoney-comblike, by means of a series ofshort horizontal' pipesor ducts by which-thefair was directed onl tothe parts to l be cooled.

"provide aradiator or cooler inwhi l the rectly about thecourse taken bylthe current- `pipes chamber, so that l the water The object 'of mypresent inventio A is to maximum, coolingsurface isfdispojsed di-` ofair drawn into,` circulatedround, and driven out of, the coolingYchamber.

The invention consists essentially. in` pro viding at the `front andback of; the radiator annular chamber;v concentric ends with a larger.4concentric chamber di-` vided Y diametricallyby` partitions into two fcompartments, andv 0r passages. from the main. annular to be cooled-'is.caused to liiow from-the `upper com fartment of saidconcentric chambersthrong the.u'p

per haliof the series of radial tubes tothe `inner` annular.`chamberaand thence through leniental cooling havingv communicatingl dabout. the corrugated surface e.

the lower half of the radial tubes into the lower compartment from whichit discharges into the body of the radiator and circulates about themain annular chamber.

ln order that my inventionlmay be better understood reference will bemade to the accompanying drawings, tion of a radiator or cooler'constructed in accord ance withthe present improvements and suitable`for use upon an ordinary motor car.

Figure 1 is a rontelevation with part of the right hand half .brokenawayor in section for the'sake of clearness. Fig. 2 is a similar view. toFig. 1, but taken from the back ofthe radiator. Figsl is a transversevertical section taken `through the i. ain annular chamber ofl theradiator, and Egg, centralsectional yelevation through the entire devicebut taken at right angles to Fig. 3. Like letters of reference indicatethe same partsin the various figures, and it maybe ere noted that thethicknesses of sheet metal from which the radiator is made have' beensomewhat exaggerated f'or, purposes of clear illustration.

a is the main annular chamber supported upon .the baseer tank b and intowhich the water to be cooled from the motoris forced through a pipe c,Figsi?. and 14, b means lof a circulating pump ofy any well nown formand not shown.v in the. drawings.

d (Fig.l 2) is the dischargepipe* from the base or tank band from whichthe cooled water is returned to the' .engine cylinders or other parts ofthe motor'for fresh use,a constant ,circul ation being thus V maintainedand which are in illustrafrequent changing' -or replenishing of thewater obviated.

lnl the form of my invention illustrated I .preferably formthe'inne'r'surface e ofthe annular chamber c from corrugated sheet.metal so that an increased cooling surface is insured.
